Models with one-to-seven steps feature spring-loaded 3" casters that compress to engage rubber-tipped legs, which provide traction and secure the ladder firmly in place when in use.

Models with eight or more steps feature 4" casters and our exclusive Ezy-LockÂ® system, which plants ladder legs firmly to the floor when pressure is applied to the bottom step. (Also standard
on 6020H, 7020H, and on 6- or 7-step models with deep step option)
